Question

Write the formula to calculate the speed of a body moving along a circular path. Give the meaning of each symbol which occurs in it.

Answer 1

1. In order to calculate the speed of the body along a circular path, one should divide the circumference of the circle by the time (t) taken to travel around the circle.
2. Therefore the total circumference of the circle = $2\pi R$ Where, R = Radius
3. Now the speed is given as $\frac{2\pi R}{t}$.
4. $2\pi R$ is the circumference of the circular path and is the total distance covered in one revolution.
5. $T$ is the time taken to complete one revolution and is called time period.
